Participants

Reaction Steps

0.35 mL (4.50 mmol) methanesulphonic acid chloride are added at RT to a solution of 1.50 g (4.12 mmol) 1-{4-[5-(4-chloro-phenyl)-pyridin-2-ylethynyl]-phenoxy}-propan-2-ol and 1.14 mL (8.20 mmol) triethylamine in 80 mL THF and the reaction is stirred for 3 h at this temperature. The solvent is eliminated i.vac. and the residue is combined with 40 mL tert-butylmethylether and 60 mL water. The precipitate is suction filtered and further purification is carried out by column chromatography on silica gel (EtOAc).
